I have seen four guns sleeved in this fashion and one had no cut line in the top or bottom ribs now either the ribs where removed from the gun before the front barrel section was cut and removed or the ribs where also welded. The good thing about the work being undertaken here in Britland is that the gun must be submitted for proof and if the gun passes proof firing the barrels are stamped “SLEEVED” with no exceptions even if you can not see the barrel joints you are left in no doubt that the gun has sleeved barrels.
